            Bug ID: 8676
           Summary: pthread robust mutexes don't behave as expected when a
                    process dies
           Product: uClibc
           Version: 0.9.32.1
          Hardware: Other
                OS: Linux
            Status: NEW
          Severity: major
          Priority: P5
         Component: Threads
          Assignee: unassigned at uclibc.org
          Reporter: khalil.mohamad at gmail.com
                CC: uclibc-cvs at uclibc.org
  Target Milestone: ---

When a process holding a robust mutex dies, the next thread that tries to lock
the mutex should get an error (EOWNERDEAD). I do not see this happening. This
is running on a MIPS platform. The calling thread gets blocked in
__lll_robust_lock_wait ().
